Direct replacement for HP Slimline

The myVolts 420W TFX unit fits HP Pavilion Slimline s5122f s5123w s5150t desktops. It supplies 420 watts through a 20+4 pin motherboard connector, a 4-pin CPU connector, two Molex, a floppy and two SATA plugs. An 80 mm double ball bearing fan handles cooling.

Upgrade from 250 300 320 or 350 watt units

The supply replaces original 250W 300W 320W or 350W PSUs in the listed models. The jump is worthwhile when added drives or a discrete graphics card push the old unit past its limit. It is not for builders who need more than 420 watts or a different form factor.

TFX form factor drops into the same chassis

Installation uses the existing mounting points and the standard 20+4 pin layout. The 100/240 V input auto-ranges so no voltage switch is required. The only common issue is cable length in deeper ATX cases which this TFX unit does not address.
