Sneaking suspicion that my PSU is unstable...

post #1 of 28
Thread Starter 
Turbo OC'd up to 3.8gh - 4ghz while playing BF3 on Catalyst 13.4s. Rig just restarts after about 5 min.....leads me believe its a unstable PSU. Never had this problem until now. Been running the 13.4s since release and dint see much issues. Could my PSU be unstable? Its only a 500w with 2 18a rails.

Wow thats the 3 one in 2 days

Not trying to be rude or insult you but that PSU is not very good
Warning: Spoiler! (Click to show)
Build Quality

Externally the OCZ 700W ModXStream Pro is a fairly subdued semi-modular design that looks good. The unit has a nice finish, well sleeved cables, good quality modular cables, and a large overhead fan. However, once we open the unit we find that OCZ 700W ModXStream Pro looks very much like a cheap group regulated unit. This is further compounded by the fact that the unit has some questionable component selections in the mystery "Rec" capacitors. Good capacitors only add slightly to the total cost of a unit so why even something along the lines of Samxon or at the very least Teapo was excluded from this build is bewildering. Further, the unit only features a 3 year warranty and with questionable capacitors this is hardly reassuring. Also related here is the unit’s "documentation." The documentation that came with the unit is simply a waste of time. This fact is punctuated by the power distribution table at the back of the manual was never actually finished by whomever was annotating it. The only upside to all of this is most of the information about the unit is printed on the packaging, but still sans a correct power distribution table as these are genuinely useful. They are especially useful when units do not follow the ATX12v specification or EPS specification for 12v power distribution such as this unit.

That model is... not very good (to put things lightly).

It's a FSP-built budget model with all CapXon capacitors rated to only 85*C (105*C is the standard for better PSUs), the PCIe wiring is 20AWG (18 is the minimum gauge that should be allowed), and overall it's just "meh" at best. See the Hardware Secrets review for a more detailed summary.

If you do decide to get a new PSU, Rosewill's CAPSTONE 550-M is $72 shipped when using promo code EMCXRXL27...

To be honest the PSU is about 4 years old. I am reusing it from the MIL build in my sig. biggrin.gif

The one thing I don't like about the Fortress is that some of its secondary capacitors are from Teapo. Sure they're no CapXon, but still I'd prefer all electrolytic capacitors to be Japanese-brand like the Capstone has.

I'll reiterate the Rosewill CAPSTONE 550-M which is currently $72 shipped when using promo code EMCXRXL27.

That quite literally is your best choice in that wattage and price range, and there's no MIR hoops to jump through.
