    • Definitely your money's worth for a reliable mid-sized power supply
Style: 80 + White Size: 500W
This is a moderate power supply, and non-modular, but it is very inexpensive for what you get. I was building a lower end gaming rig. Nothing like the newest GPU, not the latest and greatest CPU. But, the case needed a power supply. I didn't want to buy anything fancy, so I spung for a brand I have used before and I got this. Install was simple it fit the existing slot just perfect, screws line up as expected. It had more than enough power cables for all my needs, and adapters that I didn't need incase I add hard drives or other things in the future. It is quiet, I can't hear the fan running. It runs flawlessly, at least I have no reason to think it doesn't. It is one of those things you don't notice when they are working properly, and I don't notice this at all. It just works. And for the price, it is a deal. ... show more

    • Awesome value in the 600w or 850w
Style: 80 + White Size: 600W
have used these in a back up gaming pc build for my son and daughter and they are fantastic value In a 600w units!!! I also a 850 gold for my RC battery charger. My charger when I'm charging my 2-3s 5000mah packs in parallel 6 batteries per channel on both channels so 12x 3s 5000 mah lipo packs I'm charinging at 70 amps. My Icharger 406 duo is capable of 40 amps per channel and 70 amps if running both channels. So it's pushing out 840watts during the charge cycles and it handles it with no issues what so ever. No thermal issues when demanding 840 watts from it contentious and voltage stays locked in. The 850w gold I've had for seems about 2 years now and it's used to charge pretty much every single day. Some times it's 12x 5000mah packs parallel charged one set after the next when my kids and I are flying and or driving rc cars, boats, planes.. my icharger 406 duo and this power supply do very well together for rapid charging of the 2-3 cell lipo packs from 2200mah to 5000mah. For me being as close to the wattage as I am, pulling 840 constant @70 amps out of a 850w unit I fully expected to have some thermal issues and figured ide just charge at 60amps if it's having trouble delivering the 70a constant. But shockingly it handles 840w constant and has for two years or more without issues. Now I will say when the charger is in constant current part of the charging and it's putting out 70 amps of charge current the unit will get pretty dang warm but nothing to serious, at room temperature of 72F during a 70 Amp charge on 5000mah packs to where it's sustaining 840 watts of demand it will get up to maybe 110F but with a external fan blowing on it the temps will stay in the 95-100F range. For the 50 bucks I paid for the 850 gold it's been a mega good value for my needs. Reliable, quiet, smooth current delivery, very consistent voltage under high load... it's just been a dang good power supply as have both the 600w units in the back up gaming PC builds for my son and daughter. I never would have thought that the 850 watt gold would have been able to sustain 12v/70amp demand consistently as it's to close to its max wattage, I totally expected that I would have to back the current down to 60a so that would be around 720 watts for it to not have thermal issues with the power demands. It has done it for 2 years or more now and never skips a beat! If you have a computer build that needs a 850w supply I would absolutely say the 850w gold would do you a fantastic and reliable job! Computers put no where near the constant load on a unit as a high power lipo battery charger and it handles it without issue so I have no doubt it would do the same in a high demand PC build. I'm sure there are better built units out there, I'm sure there are units that deliver slightly cleaner power but at the price I don't think any other unit comes close to these. Buy one and you won't regret it, they are rock solid values and high performance units. ... show more

The Thermaltake SMART 600W is an excellent power supply that delivers steady, clean power with no issues at all. Installation was straightforward, and all the cables were the right length for a clean, organized build. It runs quiet and cool, even under load, and the 80 Plus certification gives peace of mind knowing it’s efficient and dependable. I’ve been running my system daily with no hiccups — rock-solid performance all around. If you’re looking for a reliable, budget-friendly PSU that doesn’t cut corners, this one is a great choice. Highly recommend it! ... show more

Good little psu for my office pc build. Will be getting another for my bench rig. Just a basic psu but works fine and is quiet.

    • Good value for the price, but with caveats.
Style: 80 + White Size: 600W
I picked up this Thermaltake SMART 600W PSU because it offered 80 Plus certification and seemed to check all the basic boxes for a budget build. It indeed delivers power, and for lighter to mid-level systems, it works without obvious problems. Many users also report quiet noise levels and a full complement of connectors. That said, there are several compromises you should be aware of: It’s a budget-tier unit. On forums, users mention the SMART series lacks robust protections (OVP, OCP, surge handling) that one would expect in a higher-tier PSU. If you’re pushing near 600 W load or using a high-end GPU + overclocked CPU, the lifespan and reliability might be questionable. “For low power PC’s they are ok ish at best.” It may serve fine for a standard build (office/gaming moderate), but for serious loads or long-term durability, one should consider investing more. Some reviews note the manufacturing changed between revisions, so quality may vary. Verdict: If you’re building a moderate spec PC and want decent value, this PSU is acceptable. But expect trade-offs: less headroom, fewer protections, possibly shorter service life. For mission-critical or high-end builds, it's better to step up to a stronger unit. ... show more

    • Great choice for $600 and below PC's
Style: 80 + White Size: 500W
Don't believe the hate, this power supply has never failed me. I've bought it used, and it always performs as expected. Top budget PSU in my opinion. The PSU can handle 3070s, and the cables aren't too stiff, which makes the cable management easier compared to other options.
