    • Worth it for the price
Style: RM (2023) Size: 650 Watts Color: Black
Bought to replace a different unit that gave out on me not long after purchase. So far it has been amazing. As simple as any other modular unit to install, though the cables are more stiff than I’m used to. Connectors work as expected. Smaller than expected, but fits within standard cases ok enough. Looks good. Manages heat perfectly for my needs. Minus one start for a small but noticeable click made when the unit powers on and off. No other sound, though, so it’s something I’m willing to overlook. All together was a fantastic investment for the price, and I hope it lasts. ... show more

when my old noname psu started to make trouble, i did some research, mostly at cultist's psu tiers list and have chosen this psu - tier a, available and most reasonable price, (750w, atx 3.0 & pcie 5.0 for future proof for some planned midrange rtx 5000 gpu) until this psu arrived i used some replacement psu (tier f) from computer lab guy . replacement psu was actually new one with box. so essentially i have experienced using 2 new out of the box psu recently. i write all this to talk about coil whine. f tier replacement cpu started quiet and after 1 hour loud coil whine began. i had just turn off pc at night. i didn't really care because i knew it was a temporary one. interestingly, after 1 week of coil whine - it mostly disappeared and tier f psu worked almost silently. after this cpu arrived - it had similar coil whine pattern: start silent, then some period of coil whine, than silent. probably because it's tier a - coil whine period was much shorter - 2-3 days. so people complaining about coil whine probably should give a psu some chance before rma. except that, psu is just working (now it's 1 week since installing). my general load is way below 750w, probably less than 20% of it, so psu fan is just idle not spinning - best outcome for silence. ... show more
