Great value power supply 04/29/2014
This review is from: Rosewill Stallion Series RD700 700W ATX12V V2.3 SLI CrossFire Power Supply
The PSU OEM is Solytech. This is a pretty decent power supply for the price. I would call it more of a 600W PSU, and I will list why. Even though it doesn't have APFC, at least it isn't half bridge. It uses double forward topology
First off, this thing has beefy primary silicon, good for up to 700W, two 1000µF 200V caps on the primary (voltage doubler, so 500µF usable, good for 700W)
Full input filter
Very nice fan
Good circuit protections
low quality capacitors
Almost inadequate 12V rectifiers
The heatsinks for the silicon are on the small side for a 700W unit, which is why I don't recommend using this unit at full power.
Regarding the 12V rectifiers, it uses two 30A schottky rectifiers in parallel. This doesn't mean they're good for 60A total, as they are just in parallel. I'd guess together they could safely pump out about 50A, which is just below the 56A rating. It would help if they were TO-247 parts instead of TO-220. I'm saying this to be safe, as that heatsink probably gets very toasty around that amperage.
@ Anonymous. Don't be a moron. Just because it doesn't have PFC doesn't mean it can't handle fluctuations in the AC. That's what an input filter is for. Ever heard of that? All APFC does is correct the power factor, and make the input auto detecting. This unit has a better than average transient filter, with 4 Y caps, 2 X caps, 2 coils, 2 NTC thermistors in parallel, and 2 MOV's. This is plenty to filter spikes in the mains. And actually, I'll have to respectfully disagree about PFC reducing failure. PFC circuits are more complicated. I've seen many PSU's PFC circuit fail, usually the PFC booster coil shorts which blows the transistors, and then the fuse. If anything, it's more prone to failure. Input side failure is rare in non PFC PSU's, although more of the high quality manufacturers make APFC units. Obviously, there are plenty well made PFC units out there. Here in the US, no sort of PFC is required yet (PPFC or APFC)
This would be a great budget PSU for even a high end system. Just don't expect it to last forever.
