Choosing the right power

[Cobalt89]

Hello everyone, I'm new in the forum.
And I have the following problem with choosing the correct power supply such as watts. I want to emphasize that my PC is with low specifications.
I'm interested in what energy it's going to have whit all my components inside and is 350w PSU whit 80 % efficiency will be enough to handle it without making any extra problems.
Here are the components i use;
1. Motherboard - Gigabyte h81m-s2pv socket 1150
2.GPU - MSI Geforce GT1030 Aero Itx
3. Processor - Intel Celeron g1820 socket 1150
4 hard drive - x2 One Seagate barracuda 5200 RPM and samsung momentus 5200 rpm
5 Fan controller- NZXT Sentry 2 for now whit only one 140 mm Fractal Design fan. I have attached one more back case fan, 92 mm Arctic and one stock cpu cooler.
6. dvd rw
7. PCI E x1 WI FI module
8. RAM - Kingston ddr 3. 8 gb
After checking in some of the popular PSU calculators, the results are.

1. Cooler Master Calc - Load Wattage: 264 W
Recommended PSU Wattage: 314 W
---------------------------------------------------------
2 Seasonic Calc - Load Wattage: 264 W
Recommended PSU Wattage: 314 W
----------------------------------------------------------
3. outervision.com - Load Wattage: 258 W
Recommended UPS rating: 600 VA
Recommended PSU Wattage: 308 W
----------------------------------------------------------
Is it possible 350 w PSU handle this PC ?
If yes, the next question, be quiet! SYSTEM POWER B9 350W 80 PLUS is it good choice.under 40 euros.?
----------------------------------------------------------------------------
Thank you all for your time reading my article and help.

Your PC will probably only take around 100W under load and probably never gonna pas the 150W. Those calculators are always way of.

Anyhow a System Power B9 350W will work, but the System Power 9 400W is a better power supply. It uses a more modern internal design, which has better voltage regulation in a modern PC.

The 300 and 350W are the same old design, get the 400W at least.

If possible a bit more like Pure Power 10 400W and up...

Do you have access to the Coolermaster Masterwatt (not MWE/Lite) or the FSP Hexa 85+?

[Cobalt89]

I have access to fsp hexa+ 400 model.

Which Zalman ZM600 is it? If it's the ZM600TX, I believe it's decent. Offers a full set of protections and DC-DC. http://www.hw4all.com/zalman-zm500-tx-500w-review-test/

The FSP hexa and Hexa + are not good. Only the FSP Hexa 85+ X50 PSUs.

[Cobalt89]

There are:
Zalman zm400 lx
Zalman zm400 le
Zalman zm600 leii
Zalman zm600 lx

There is fsp group fsp350-60apn 85+
