Which PSU is best for my system? SS-520GM vs SS-620GB

[zivlaks]

Please tell me which one to get. My rig is in my sig.

A 7950 needs only 500w in a normal rig.
That said, I like to overprovision a bit to 620w.
1. A psu will operate most efficiently in the middle third of it's range.
2. At less than full load, the fan will not need to spin up and be quieter.
3. 620w allows you a future upgrade to a card as good as a titan.

And... Seasonic is as good as it gets, it will likely deliver more power than advertised if needed.

Depends what you want to spend and if you are planning adding another gpu or not really.

As mentioned by geofelt, 600w+ is a no brainer.

Heres a few good ones http://www.newegg.com/Product/Productcompare.aspx?Submit=ENE&N=100007657%20600014023&IsNodeId=1&bop=And&CompareItemList=58%7C17%2D151%2D095%5E17%2D151%2D095%2DTS%2C17%2D151%2D088%5E17%2D151%2D088%2DTS%2C17%2D139%2D012%5E17%2D139%2D012%2DTS%2C17%2D151%2D118%5E17%2D151%2D118%2DTS

I would go Seasonic or Corsair HX/TX

For a system using a single AMD reference design Radeon HD 7950 graphics card AMD specifies a minimum of a 500 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 30 Amps or greater and have at least two 6-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most critical factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

The XFX Pro Series 550W (P1-550S-XXB9) power supply unit, with its maximum combined +12 Volt continuous current rating of 44 Amps and with one 6-pin and one (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single Radeon HD 7950 graphics card.

The XFX PSUs are all made by Seasonic.

If you want a semi-modular PSU then the SS-520GM will be fine.

I don't have access to XFX in my country. Only these brands:

LC-Power: http://itsvet.com/proizvodi/lc-power/comp_comp_powersupply/producer/204

seasonic: http://itsvet.com/proizvodi/seasonic/comp_comp_powersupply/producer/725

raidmax: http://itsvet.com/proizvodi/raidmax/comp_comp_powersupply/producer/1172

Only PSUs that have a price in euros (number in red above them) are available. I wanna spend about 80-90 euros or less (its 100-120 dollars).

The Seasonic SS-520GM will be fine if you're not doing excessive overclocking.

If you're overclocking the FX-8350 to 5GHz then you should get the Seasonic SS-620GB.

 

[Dark Lord of Tech]

XFX is made by Seasonic , so get a Seasonic , you can't go wrong.

 

[beanoslim]

The SS 520GB and SS 520 GM are the same PSU with the GM being modular.

The SS 620GB and SS 620 GM are the same PSU with the GM being modular.

Both are fine so it depends if you want modular cabling, personally I would go for the 620GM for 100 euros.

If not the 620w non mod is basically the same price as the 520 mod unit, if modular isn't an issue go for the 620w unit to cover yourself.

With 100 € best psu is Super Flower Golden Green modular.

Mon modular is cheaper.
