FSP Epsilon 700w ATX PSU

Looking Inside

Looking Inside

As with all power supplies that pass through Overclock3D, I'll be taking a look inside the Epsilon. By doing this I should be able to get a good idea of the overall build quality of the unit and how it is likely to perform in our tests.

I must admit being rather shocked when I opened up the Epsilon. Knowing that FSP have a reputation for making good power supplies, along with the fact that this unit was rated at 700w, I was expecting to see some beefy components inside. However, I was rather disappointed to see small components, small and poorly designed cooling capabilities and generally a power supply that looked like a generic 400w model.

FSP Epsilon Adjustable Pots

On the upside, one thing I did spot inside the Epsilon 700w was an adjustable potentiometer (pot). Pot's can be used to adjust the voltage output by the rails on the power supply, and can come in handy when voltages droop outside of ATX specifications.

FSP Epsilon Fan

Cooling the Epsilon 700w is a 12cm fan manufactured by Protechnic Electrics. The maximum speed of this fan is 2500rpm at 38.3dB when running at 12v. FSP have also gone to the trouble of including a fan controller which adjusts the speed of the fan based on the PSU load.

Looks a decent, solid, if not a little strange acting PSU Quote

Yeah it threw a bit of a 'hissy fit' on our load tester, but managed to do pretty well when plugged into the test rig.Quote

Glad it started working for you correctly mate! FSP usually makes a great unit. My blue storm was the heaviest and most solid psu I'd ever had for the price I paid for it.Quote

the hiper uses the same connectors. Just out of curiosity, will you have various charts/graph diagrams comparing all the psus you've reviewed?Quote

05-07-2006, 07:26:34


Yes, once we've got a few more manufacturers on board, i will create a comparison chart so we can truly see what PSU takes the crown Quote

You gotta get a Tagan 1100w to review. Now that'd prolly take the crown *drool* Quad SLi connectors are so sweet, especially the way Topower sleeves them. Topower makes most of the OCZ PSU's, Tagan PSU's, and I think the Mushkin PSU's too... gotta check tho.

Ya, Mushkin's is Topower made to Mushkin's specs.

A funny little note is that OCZ's newer Gamestream PSU's are the FSP Epsilons Quote

FORTRON / FSP Power Supply Units are unreliable hardware devices.

Failed just after 784 days of normal use (about 3500 hours only)!.Quote
